Lack of sympahy or Assitance from Management

I have been overcharged for my stay and have been battling to get in contact with a manager. I have phoned and left massages for the manager to return my call. I finally got hold of the manager 1 month and 1 week later who advised that refunds are only done on a Wednesday and thereafter it takes 2-7 days. This is unacceptable and terrible service
